Measurement uncertainty provides a quantitative reference to choose appropriate instruments and measurement methods. This paper focuses on the measurement uncertainty introduced by measurement instruments in frequency domain channel measurement systems. For frequency domain channel measurement, the measurement instrument, Vector Network Analyzer, need to be calibrated before measurement. The uncertainty...
This paper investigates the measurement uncertainty introduced by measurement instruments in frequency domain channel measurement systems. The uncertainty is a quantitative indication of the quality of the measurement results, so it provides a quantitative reference to chose appropriate instruments and measurement methods. The uncertainty analysis is based on Monte Carlo method. To account for the...
In this paper, a monolithic self-calibration method is proposed to reduce DC offset of output voltage in buck converter with adaptive on-time control. The calibration system senses the average output voltage of converter and dynamically reduces offset by digital tuning the comparing reference. DC offset at output voltage caused by parasitic ESR, ESL of filter capacitor and loop delay can be effectively...
